STINNER Victor <vstin...@python.org> added the comment:
"On BSD, there's a library function called fls() that we could use, and GCC provides __builtin_clz()." See also rejected bpo-29782 and GH-594. If someone wants to experiment that, I suggest to add Include/internal/pycore_pymath.h, move _Py_bit_length() there and convert it to a static inline function. Since the code is now unified, it makes a little bit more sense to add specialized code, *if* the code is not too complex. I'm still not sure that GH-594 is worth it, since it was not possible to see the speedup on a microbenchmark :-( ---------- _______________________________________ Python tracker <rep...@bugs.python.org> <https://bugs.python.org/issue31031> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
